I purchased two of these, installed them with bolts and even used cement to keep them in place. After one week one of them fell over and broke.I purchased these for my mom for Mother’s Day, I contacted wayfair to see if they could replace the broken one and they said I was past the 30 days.(it has been 45 days) The screens are 50 lbs and should not be that easy to fall over. I will look elsewhere to purchase from now on.
